Russian scientists have invented a concrete that is strong
and has considerable flexibility, which allows it to withstand much more
pressure than ordinary concrete and does not break.
It uses pure cement to strengthen ordinary concrete but
cement content in new concrete has been reduced to 60%, while the remaining 40%
add rice residue, limestone crushing remnants and silica sand have gone
As a result, two things happened: first, the strength of
such concrete remained the same as that of conventional concrete resists.
During the experiments it was found that this new concrete
is capable of withstanding 6 to 9 times more pressure than conventional cement;
after which it starts to crack.
The feat was carried out by scientists from the Military
Studies Center at Russia's "Eastern Federal University" who wanted to
create a construction material that was low-cost and strong enough to resist
earthquake-resistant buildings to make it even safer.
Full details of this have been published in the latest issue
of the research magazine called "Organic Materials: Applied
Research."
